Welcome to a place of vision and beauty. Welcome to the world of space art.
I have a reasonably educated critical eye and find it can be applied to original paintings and equally to digital art images because the same rules apply.
Every work is enhanced by good composition, complementariness and wide tonal range.
What is most often lacking in digitally created space art is the magic of loose edges.
For some reason photo realism appears to be attractive to the software creator and yet the image made is to appeal to a human eye which does not see everything in the same sharp focus.
That's an excellent point, Marie. I noticed that myself.
Egad - people live here! :D
Yikes! They do!
Intent, and the Artist's approach to his or her problem solving method(s).
I think sci-fi artists try to expound on the infinity of space in their mind
And try to duplicate or replicate .what the imagination has offered.
